` Be it known that I, PIERRE BRUNET, of the l city of Toronto, in the county of York, in the effective railway snow-plow; and it consists in the peculiar construction, arrangement, and

` combination of parts, as hereinafter more fully described and claimed.

` plow nowin use is that in pushing off the snow it packs it into a solid mass, thereby forming a wall, which constitutes a resistance which the greatest power possible to be placed behind i .i y the plow is incapable of overcoming.

In the drawings like letters of reference indicate corresponding parts in'each figure.

A is a hollow chamber, shaped very much like the water-tank on the tender of a locomo- V tive, but having a pointed front, a, similar to i l the front of an ordinary snow-plow. rIhe hollow space B between `the bifurcated tank A is intended tobe occupied either by the men in charge of the plow, or, if it is found necessary to weight the plow, this space may be lled` `withiron or other metal.

C is a furnace placed belowthe floor of the space B, and situated between the bifurcated tank A, which tank extends from the bottom `of the plow up to its top, and is intended to be` lled with water.-

D are lues leading from the furnace O A at or near its bottom, and extending from the furnace C to the vertical flue E,which ue j i passes up through thefront aof the bifurcated `45` tank A. I have stated that the tank A extends from the bottom of the plow to its top. In sucha casethe water within it would of coursesurround the iiues D. In Fig. 3, however, I show the flues D at the `bottom ofthe `tank A, the top of the dues forming the bottom `of that portion of the tank containing the water. In such an arrangement the heat of the flues D acts directly on the bottom portion of the sides of the tank A,whilc the water in the upper portion of the tank is heated sufficiently by the iiues to impart the necessary warmth to the sides of the upper portion of the tank A. In such an arrangement the lower part of the tank would be warmer than its upper portion, which may be found advisable, as the snow immediately around it will be probably harder to remove than its light upper surface.

F are steam-pipes extending one from each side of thebifurcated tank A down `through the plow to a point immediately above the rail G. These pipes should be provided with suitable cocks, and are intended to direct the steam from the tank A onto the rail for the purpose of blowing off the snow a-nd rendering each rail as smooth and clean as it is in summertime.

In order to shovel up the snow toward the pointed front of my plow, I provide a fiat shovel, H, formed on the bottom of the front of the plow. rIhis shovel `will raise the maj or portion 'of the snow clear of the track, leaving but litshould be made, as it is self-evident that the tank should ofcourse be made of metal; nor do I give any dimensions or specify in detail the exact construction of my plow, as these are matters which will be regulated by the nature of the railway that the plow is to be applied to, and are questions of mechanical detail which it is not necessary for the inventor to specify, the foregoing description, with the drawings, being sufficient to enable any skilled mechanic to understand my invention, and to build a snow-plow according to its principles.

What I claim as my invention is 1. A hollow bifurcated chamber or tank, A, shaped substantially as shown,` and having flues D and E arranged within it, as described, in combination with the furnace C, substantially as and for the purpose specified.

2. In a snow-plow, and in combination with the furnace C and the bifurcated tank A thereof, having flues D and E arranged within it, as described, the pipes F, connected with and extending one from each side of the bifurcated tank through the plow to a point immediately purpose specified.4

3. The combination of the bifurcated tank combination with a. pipe taking steam from the A, having pointed front a, ues D and E, fur- Steam-space of said tank and directing it upon 1o nace C, and shovel H, all constructed and arthe mils, substantially as described. ranged and operating substantially as and for 5 Iche purpose specified. PIERRE BRUNET' 4. In a snow-plow, the tank A, provided j Vitnesses: with a suitable furnace and nue, and having CHAS. C. BALDWIN, its sides constructed to act as a snowplow, in l F. B.
